Please click on "More Information" for flow chart.

The chart above shows the relationship between head height (the height difference between the pump and the final height that the water is lifted) and Gallons Per Hour (GPH). To determine which pump model is recommended for your waterfall or fountain, find your desired head height in the left column and follow that gridline right to your desired GPH along the bottom. The curved line to the right of that intersection represents the recommended pump model.

The flow chart represents the water pump operating under ideal conditions, using the recommended sized tubing with no bends or elbows and operating in a free-flow manner. Situations that will reduce the output of a water pump below the above ratings include: using tubing with a smaller diameter than recommended, any bends or elbows in the return line, and placing any restrictions on the output side of the pump. These restrictions may be in the form of a filter and ball valves used to control the flow rate.

It is difficult to determine the effects that restrictions may have on the output of a water pump. Choose a model of pump that offers a higher output than previously anticipated. By doing so and installing a ball valve on the outlet side of the pump, you will be able to not only control the water flow, but will also be assured that you will have sufficient water flow once the unit is installed.

Pumps run 24 hours a day and are the chief piece of equipment responsible for keeping your pond healthy. Selecting the correct pump is essential for a healthy pond. Here are some tips to help you pick the perfect pump.

Are you considering a waterfall or stream in your backyard, but don't know where to start? Creating a plan and having the right equipment goes a long way toward saving you time and money. These tips will help you get started.

Not a great pump
Took 10 days to get here. Claims Thermoplastic exterior is corrosion-proof. Yup maybe, but the motor exterior is ACTUALLY metal, gets hot and overheats. Poor design or application for a pond. I should have spent a few more $$ and have gotten a better pump. I would've sent back but pond had already been 2 wks without a pump, so I just kept it. It's a low end pump.

I connected the pump and it runs then quickly overheats and shuts off.
I connected this 3/4 hp LIfeguard Sea Horse pump and checked the voltage (115v 10.5 amp). The pump it replaced was 115v 13.8 amps but was 1 hp. The pump primes and runs for 30 sec then overheats and shuts off.

Thank you for your question. In regards to the connecting attachments, nothing but the pump is included. We suggest that anyone who buys this item hire an electrician to hard wire this in. And as for the voltage it is actually 115V.
